In general, it is advisable to choose plants that are native to the area in which you live, since these are usually more resistant to local pests and diseases. It is also important to note that proper plant care, such as proper watering and fertilization, can help strengthen their natural resistance against pests and diseases.

Possible common pests in a garden:

  • Insects: such as aphids, whiteflies, caterpillars, beetles, mosquitoes, flies, bedbugs, aphids, thrips, and ants.
  • Mites: such as tiny spider mites that can damage plant tissues.
  • Snails and slugs: they can chew leaves and plant shoots.
  • Rodents: such as squirrels, moles, voles, or mice, can damage the surface of plants or underground roots.
  • Birds: such as pigeons, sparrows, blackbirds, and starlings, can damage crops and peck at seeds and fruits.
  • Fungi: which can cause leaf spots, root rot, and plant diseases.
  • Weeds: like weeds, they can compete with plants and steal nutrients and space from them.
  • Verticillosis: a disease that affects crops and results in yellowing leaves, deformities, and death of plants.

It is important to care for and treat lawns and gardens safely and with proper procedures to control unwanted pest infestation.

Each of these pests can cause different types of damage to plants, from yellowing and wilting leaves to holes in leaves and fruits. It is important to identify the specific pests in your garden and find specific pest control solutions to keep your garden healthy and vibrant.

Tips to control the infestation of unwanted pests in gardens.

There are several suitable procedures to control the infestation of unwanted pests in gardens, which can help maintain the good health and appearance of plants, and prevent the spread of diseases and pests to other crops. Some of these procedures are:

  • Regular Inspection: It is important to regularly inspect plants and soil for signs of pests and diseases, such as damaged leaves and fruits, spots, holes, bite marks, droppings, insects, and larvae.
  • Manual removal: It is useful to manually remove pests that are present on the plants, such as aphids, scale insects, caterpillars, slugs, and snails, among others. To do this, you can use gloves and tools such as pruning shears or brushes.
  • Biological control: It is possible to introduce beneficial organisms such as predatory insects, nematodes, entomopathogenic fungi, and bacteria, among others, to control pests naturally and without affecting plants and other living beings.
  • Traps: Traps with pheromones and other attractants can be placed to effectively capture and control pests.
  • Natural pesticides: Natural pesticides such as essential oils, insecticidal soaps, diatomaceous earth, and garlic solutions, among others, can be used to reduce the presence of pests.
  • Crop rotation: It is important to move plants and crops from time to time to avoid the accumulation of pests and diseases in the soil and roots.
  • Proper maintenance: It is important to maintain proper care and maintenance of the garden, including cleaning of dry leaves and branches, regular pruning, watering, and proper fertilization, to avoid stress and vulnerability of plants to pests and diseases.

Pest control in gardens can be carried out effectively and naturally by implementing appropriate procedures to ensure the health and appearance of plants and maintain a healthy and balanced environment in the garden.

Which ornamental plants are most resistant to pests?

There are several ornamental plants that are known for their resistance to pests and diseases, such as:

Lavender

Famous for its soothing fragrance, lavender is more than just beautiful—it’s a natural pest deterrent. Its strong aroma and high concentration of essential oils repel insects like mosquitoes, moths, and flies. These same oils also help protect the plant from certain fungal diseases. Plant lavender in sunny, well-drained soil to enjoy both its beauty and its protective benefits

Chrysanthemum

Chrysanthemums are vibrant and long-lasting blooms, but they also have a hidden superpower: they produce natural pyrethrins, compounds widely used in organic insecticides. These substances effectively deter ants, roaches, fleas, and other pests. Grow them in sunny spots with regular watering for a pest-resistant burst of color.

Geranium

With their bright flowers and pleasant scent, geraniums double as a natural insect repellent. They contain antibacterial and antifungal compounds, giving them strong defenses against diseases. Perfect for garden borders or potted arrangements, they thrive in sunny locations and moderate watering.

Catnip

Best known for its effect on cats, catnip also works wonders as a pest-resistant plant. It contains nepetalactone, a compound that naturally repels mosquitoes, flies, and even cockroaches. Easy to grow and low-maintenance, catnip flourishes in full sun or partial shade.

Calendula

Often called pot marigold, calendula adds cheerful orange and yellow hues to any garden while keeping pests at bay. Rich in carotenoids and flavonoids, it not only resists insect damage but also heals quickly from minor stress. It’s ideal for companion planting, especially near vegetables.
